ShuntCheck is an aid to the detection of flow in implanted cerebrospinal fluid (CSF) shunts. ShuntCheck includes Micro-Pumper, a component which may be used to temporarily increase CSF flow in suspected non-flowing, patent shunts during the ShuntCheck test. ShuntCheck cannot alone diagnose CSF shunt function or malfunction. The clinical diagnosis of CSF shunt function or malfunction, incorporating the flow information from ShuntCheck, should be made only by a qualified neurosurgeon.

ShuntCheck is a non-invasive device which detects flow in a CSF shunt via transcutaneous thermal dilution. The device consists of a single use disposable thermosensor array patch which is connected to a data acquisition unit (a DAQ) which is connected to a laptop or tablet computer. The device also includes a Micro-Pumper which vibrates the shunt valve during the test procedure to generate a temporary increase in flow in patent but temporarily non-flowing shunts. The shunt is cooled transcutaneously by placing an instant ice pack over the shunt cephalic to the thermosensor. The thermosensor array patch, which is placed on the skin over the shunt "downstream" of the ice, reads the change in skin temperature over the shunt as cooled fluid flows downstream and also at a two nearby control locations. Data is transferred through the DAQ and captured in the computer. If the device detects a characteristic downstream transcutaneous temperature dip, the computer reports "flow confirmed" and presents a time-temperature graph of test data. If no temperature dip is detected, the unit reports "flow not confirmed" and presents a time-temperature graph.
